Replacing a Priora resonator with your own hands: device, which one is better to choose, how to remove, how much it costs + video

The system for removing waste exhaust gases in a car is an important technical complex that performs many necessary functions: reduces toxicity in exhaust gases, reduces noise from vehicle operation, prevents the penetration of toxic products of fuel combustion into the passenger compartment of the car, participates in regulating the operational characteristics of the car, Thanks to the creation of the necessary resistance of exhaust gases, it creates a certain image of the car brand (timbre of sound, detail of appearance). On the Lada Priora, in this regard, replacing the resonator is not such a rare operation.

How much do other models cost and what are their features?

There are other options for choosing such spare parts for the Lada Priora.
In stores and retail outlets, resonators from a variety of manufacturers are sold, which differ in their cost. For example, prices for a given spare part from individual companies may be as follows:

From the company EKRIS (with an aluminized body - 2250 rubles or more, the regular version - from 1800 rubles). The advantage of a product without a special coating is the fact that this ferrous metal resonator is the best in terms of price/quality ratio.
From (from 2000 rubles). It is the most suitable original component of the Lada-Priora exhaust system at an affordable cost.
From (aluminized model - from 1950 rubles). A fairly well-known company offering inexpensive, high-quality resonators with a special durable housing coating.
Resonators of the SVD brand. Made from aluminized steel. It has a long service life (at least three times longer than the service life of conventional, painted products made of ferrous metal), low noise level, saves fuel, and has low back pressure. Is the most expensive option.

There are also many other firms and companies offering this component of the exhaust system, differing in both cost and workmanship.

Repair, or rather a complete replacement of the resonator of a Lada-Priora car, if it fails, is an important and necessary action for the proper functioning of other technical complexes of the car, as well as for ensuring truly comfortable conditions for passengers and the driver.

Main components of the Priora exhaust system

As already mentioned, this is not one element, but several:

Timing (gas distribution system) exhaust valves.
Exhaust manifold with particulate filter (catalyst).
Oxygen sensor (Lambda probe) 2 pieces.
Middle part with resonator.
Tail section with muffler.

Each of these parts must be considered separately.

Release of gases in the cylinder head

This is part of the operation of the gas distribution mechanism. A full description of this mechanism is a separate issue of engine operation. It is enough to mention here that the 8 exhaust valves open in exhaust mode and the piston pushes the exhaust gases into the system. Namely, into the exhaust manifold.

Catalyst or particulate filter in the exhaust manifold

This is one of the most complex and expensive components of the entire exhaust gas system. Essentially, this is a device for afterburning unburned gasoline particles using catalysis. For this purpose, the thin walls of the longitudinal filter honeycombs are made of a special material. Contacting them, gasoline burns (figuratively). The output is ordinary water.

Set of Lambda probes for Euro-3 system

What is Euro 3 standard? In fact, this is the level of purification of car exhaust gases. It is according to the levels of vehicle access to Europe that these systems are distributed. There are several levels:

Euro level.
Euro 2 threshold.
Euro-3 (basic for Priora).
Euro-4 (Subsequent models and the latest “Priors”).
Euro-5.

In the first option, a particulate filter was added to the exhaust system. It is mentioned above. But in system No. 2, electronics control has already been connected. A special, rather complex and expensive sensor was developed. Lambda probe or oxygen sensor. Thanks to a special coating, its resistance changes its value depending on the saturation of the exhaust gases with carbon monoxide. That is, carbon monoxide.

To more accurately understand the meaning of the Lambda probe, it is worth briefly describing the history of Euro standards. So.

To reduce toxicity, an afterburner was installed in the exhaust system (the particulate filter described above). This was the Euro system. Further, with the development of the electronic component of the control system, the idea of exhaust quality control came. And installed 1 oxygen sensor. It was placed in the system directly into the collector. Before the afterburner. This allowed us to make adjustments to the gas saturation table in the program. The system with one sensor was called Euro-2.

However, savvy motorists quickly realized that the particulate filter, which reduces engine power, can simply be thrown out. Which is what they began to do with success. Then, after the afterburner, another Lambda probe was inserted into the system. And he already informed the computer that the filter was not working. And accordingly, he again cut back on fuel. This became the new Euro 3 standard. Well, Euro 4 and 5 are just a modification of the software and replacement of fuel to the European level, respectively. The latter, if nothing interferes, should be carried out in Russia by the end of 2022.

This is what the oxygen sensors in the Priora exhaust system are for.

What is the purpose of the resonator in the Priora exhaust device?

It is also called an auxiliary muffler. It is an exhaust system pipe bent at an angle and having an extended section in one place. This makes it possible to initially smooth out the sound vibrations escaping from the engine when releasing gases.

The auxiliary muffler is located immediately behind the manifold and catalyst. And immediately behind it comes the muffler itself.

On some Priora models, two parts, the resonator and the main muffler, are made as a single unit. But the collapsible design is more convenient both in operation and in repair.

Step-by-step instructions for replacing the resonator on a Lada-Priora with your own hands

The best models and procedure for replacing low beam lamps on a Lada Priora.
Actions to replace a faulty resonator of this model are carried out quite quickly, without any difficulties arising in their sequence. Car repairs are best done using an inspection hole or a lift. As a last resort, you can lift the car body with a jack.

To carry out repairs, you will need a set of the following tools:

special penetrating lubricant;
keys, heads at “13”;
knob or ratchet;
chisel;
hammer.

A hammer and chisel are needed if the fastening nuts cannot be unscrewed from the manifold studs due to burning of the metal. To dismantle the resonator, you must carefully cut the nuts with a chisel, being careful not to damage the studs.

For self-repair, the step-by-step brief instructions for the work are as follows:

All existing threaded connections are treated with a special penetrating lubricant to facilitate their unscrewing.
The clamp, which is the fastening element of the resonator and muffler pipes, is equipped with two nuts that can be unscrewed.
The loose clamp is dismantled.
The above pipes (resonator and from the muffler) are disconnected.
The special metal sealing ring is removed.
The nuts that secure the pipe from the resonator to the catalyst are loosened. It should be noted that some car models are not equipped with this component. In this case, this stage of action is replaced by measures to disconnect the resonator tube from the collector.
The resonator rises slightly.
The hanging pillows are removed from the metal bracket. The rear cushion is released first. Next, the front one is dismantled.
Further and final unscrewing of two nuts is carried out for fastening to the catalyst structure.
The special spring washers are dismantled.
The bolts are removed. In case of repair of a car model without a catalyst, both fasteners are removed together with the springs.
The resonator is dismantled.

How to remove the old resonator

Before starting any work on the exhaust system, it is necessary to drive the car onto an overpass or inspection pit. You can use a lift or even a regular jack - you need to make sure that the car is securely fixed in this position.

And also, before starting work, it is recommended to lubricate all threaded connections that will need to be unscrewed. This is necessary so that the old fasteners can be dismantled as quickly as possible. After 10 minutes you can begin the main work:

First, the connection between the pipe and the exhaust manifold is unscrewed. This is the most difficult place to reach in the exhaust system. You can try to remove the nuts with a wrench. But in most cases, even WD-40 is not able to soften the reliability of the connections. Therefore, you have to resort to using a chisel to move the nuts out of place.
If even after the chisel the nut cannot be unscrewed, you will have to cut it off with a hammer and chisel, while being careful not to touch the stud itself on which it stands.
After unscrewing or removing the nuts, you can move one edge of the resonator to the side. You can start dismantling from the other edge.
Next, the nuts of the coupling clamp are easily unscrewed.
If the nuts suddenly become very stuck, you can cut them off with a chisel.
The resonator is disconnected from the exhaust system pipes; all that remains is to remove its body from the rubber suspensions.
After which the product is pulled out from under the car.

Resonator installation

Design and malfunctions of the exhaust system of the Lada Priora

Installation of the part is carried out in the reverse order. Compliance with the required sequence, as well as the use of the original resonator for the Lada Priora, ensures simple, easy installation of the part

Particular attention must be paid to connecting the new resonator to the muffler pipe. It is recommended to replace the special metal sealing ring between these components, as well as the clamp itself, with new ones in order to ensure the required level of sealing of the connection, reliability and rigidity of the structure

The fastening elements are clamped sequentially, without distortions in the level of the resonator and muffler pipes.

The Lada Priora resonator in the exhaust system is located, as a rule, after the collector pipe (pants) or after the catalyst

On the Lada-Priora car, it is recommended to install a resonator, which is made from stainless steel options. This circumstance allows you to significantly increase the service life of this part. Installation of such a resonator is carried out on its standard mount and no additional modifications or improvements are required in the exhaust system of the car.

Experts do not advise trying to install resonators that are intended for use on other car models. For example, you should not try to install a resonator from the domestic brand Lada-Kalina on a Lada-Priora. This is due to a number of reasons that will subsequently have a negative impact on the technical and operational characteristics of the car, and such a replacement will only turn into a waste of money, time and effort.

When installing resonators from other cars on the Lada-Priora, extraneous noise and unwanted vibration may be observed when the engine is running, which is caused by defects in the bends of the shape and size, as well as differences in the fastening of the part to the suspensions of the car body. All these points are determined by the relevant norms and standards at the manufacturer.

The main advantages of the part include:

reduced exhaust noise compared to factory;
the thickness of the partitions is 2.0 mm;
integrity and high-quality assembly of the housing (pulse argon arc welding is used);
high-quality processing of welds on the body, which includes several stages and consists of their mechanical processing, subsequent polishing and special acid passivation.

Additional characteristics of the resonator on the VAZ 2170

It is worth noting that the new resonators have an exhaust that is 2 dB quieter. This effect is achieved due to the integrity of the case and the thickness of the partitions of 2 mm. All of the above advantages are achieved due to the type of assembly and damper, namely pulsed argon-arc welding.

The final and preparatory stage is the processing of seams. The operational period depends on their quality. Seam processing consists of three stages, namely:

• mechanical restoration;

• polishing;

• passivation in acid.

The main malfunctions of the Priora exhaust tract

Resonator in the exhaust system: device, principle of operation and methods of replacement or repair

Due to the fact that the operation of these components is associated with high temperatures, the most common breakdown is the burning out of some part. This could be the gasket under the manifold, or the wall of the muffler, catalyst or resonator. A separate part is the malfunction of the particulate filter or afterburner. But they are included in the section for repairing the injection part of the car, just like the Priora oxygen sensors. In other cases, it is either mechanical damage or simple rust.

The appearance of extra holes in the system is determined immediately and for sure. The engine exhaust just becomes loud and unpleasant. There is a crackling sound and sounds vaguely reminiscent of shooting. In this case, you need to go to the inspection hole, find the hole and replace the damaged unit. Relevant video on this topic:

Resonator repair or replacement?

In most cases, it is advisable to install a new spare part, but there are exceptions. If a breakdown occurs on the road, you can carry out repairs using fiberglass or sealant, but you must understand that such repairs will not last long.

Before using them, carefully clean and degrease the edges of the burnout, remove dirt, soot, traces of rust, and grease. If fiberglass is used in the work, then after installing the resonator in place, it is necessary to let the engine run for half an hour.

Such repairs can be done with your own hands. But if we are talking about replacing the resonator pipe, then such actions should be carried out by specialists. The same can be said about eliminating large burnouts, which is carried out only by welding.

Repairing the resonator is advisable if it has received minor mechanical damage; the holes can be welded or a patch applied. If the resonator is rusty, bursts along the walls or body, it is more advisable to replace it with a new standard or universal one.

Manufacturers of mufflers and prices of analogues for Priora

The choice of Priora mufflers available to consumers is huge. Many of them differ in the name of the manufacturer's plant. Let's look at the main ones that differ in production method and materials:

Muffler made of steel with a large admixture of aluminum (Lada-Image, EDEX, PHOENIX, etc.), resistant to corrosion, suitable for all body types. Its disadvantage: the presence of welding seams in the design of the part. Price – from 2500 rub;
The sunset type of production (Phobos, NAAZ, Avtokomplekt, etc.) has the main advantage that the part is produced without welding technologies or the use of stainless steel, so it has an increased service life. The price of such a “stray” is from 3000 rubles;
Budget muffler (“VVV Tolyatti”) uses iron-zinc steel in production, is short-lived, suffers greatly from corrosion, and wears out quickly. The only plus is the price of the spare part is approximately 1400 rubles;
A separate type is stinger (spider) forward flow exhaust systems (“MUTE”? “StinGer-auto”, etc.). Advantages - a slight increase in vehicle traction, choice of high-quality materials in manufacturing, long service life.

Types and design of mufflers

Resonator (additional, front) . The resonator is connected to the collector pipe using bolts. It serves to distribute the gas flow and pre-suppress noise. The part is a perforated tube in a sealed housing, divided into several chambers. Perforation allows vibrations to be dampened due to the phenomenon of interference.
Main resonant muffler . On Priora, the main muffler is located after the catalyst. It is designed for ultimate noise suppression. Changing the cross-section of the exhaust flow in the chambers leads to the final damping of vibrations. The resonant type unit consists of several perforated tubes located in the housing.
Main direct-flow muffler . The direct-flow muffler for Priora is installed in place of the standard one. It has a slightly different design. Damping of acoustic vibrations is achieved as a result of changing the direction of flow. Also, sound-absorbing material is used in the forward flow chambers. The engine gets a characteristic sound, like a real sports car. Some Lada owners believe that the factory exhaust system does not allow the 16-valve engine to show its full power, especially when overtaking at a standing start. Although experts are convinced that installing a sports muffler alone will not solve the problem of lack of power. Either the engine needs to be modified or the entire exhaust system needs to be replaced.
An exhaust manifold . The presence of a manifold with an exhaust toxicant neutralizer is a key feature of Priora cars. In sports tuning, spider manifolds with complex geometry and physics of the structure are used.

An exhaust manifold

General information about the principle of operation and design of the resonator

The operating principle of this component is based on the use of completely closed cavities located near the pipeline, which are connected to the latter using a number of special holes.

As a rule, its body contains two cavities of different volumes, which are mechanically separated by a special solid partition. The existing holes, as well as closed individual cavities, are resonators that excite oscillations with their own frequency.

The directions of propagation of noise waves with a resonant frequency can change, due to which its effective noise damping occurs. The effect occurs due to friction in the holes present in the exhaust of gas particles.

The structure consists of two parts: the outer shell, as well as the internal structure. The product can be made entirely of stainless steel AISI 316, which is an analogue of the common version 10Х 17Н 13М2. Standard dimensions correspond to 250 mm x 100 mm. The pipe is also made of high-quality stainless steel and has dimensions of 51 mm x 1.5 mm.

The internal filling of the body of a standard resonator is simple, and the design uses features that take into account the propagation of noise waves

Features and Benefits

The main task of the exhaust system resonator of the Lada Priora car is to qualitatively dampen the sounds of engine operation, as well as vibrations arising during operation.

With the loss of the original qualities of this component, there is a sharp increase in vibration, as well as the noise characteristics of the car’s power unit, reaching their peak values at maximum engine speed. In fact, this is a regular muffler that performs the same functions, which is why it is called a middle muffler based on its location in the exhaust system.

Such a muffler has the following advantages:

effective damping of low noise frequencies;
absence of significant barriers to the passage of gases;
use does not reduce the overall cross-section of the exhaust system.

Causes of possible breakdowns, conditions for replacing parts

The main reasons for replacing the resonator on a car are as follows:

burning of the body in the center of the structure;
burnout or mechanical damage to the joints with the exhaust manifold (catalyst) or muffler;
corrosion processes.

The resonator can burn out anywhere or undergo unwanted corrosion

As a rule, the following reasons are to blame:

sudden changes in external temperature;
contact of exhaust system components with reagents, salt, and moisture;
accumulation of moisture condensate in the resonator;
the presence of various chemical aggressive compounds in the resonator.

A faulty resonator when driving is a source of discomfort for the driver and passengers of the car. Other road users will also have a negative reaction to the operation of a car with a similar malfunction, since the movement of such equipment will be accompanied by loud noise.

Thus, signaling factors about a malfunction of the exhaust gas exhaust system of vehicles, in particular the Lada-Priora resonator, are:

increased noise when the engine is running;
a noticeable decrease in the power of the power unit (decreased traction, acceleration);
intermittent engine operation (jumpy idle speed);
entry of exhaust gases into the passenger compartment of the car;
presence of black deposits on parts (smoke soot).

Due to its design features, full-fledged repair measures for this part are impractical, so experts recommend replacing the failed component.

What is a resonator

When people hear the loud roar of a car passing by, they think that the engine is running so loudly. Although the reason for the sharp sounds when applying gas lies not in the engine, but in the muffler of the car.

A resonator is one of the parts of a car's exhaust system. It is he who is responsible for gas removal and reduction of exhaust noise. In addition, it lowers the exhaust temperature and dampens gas pressure.

If you look at the entire diagram of the exhaust pipe, the resonator will be located approximately in the middle. And if a sharp and powerful sound comes from the pipe while driving, then this mechanism is solely to blame.

Node device

Structurally, the resonator consists of one large body, in the cavity of which there are two or three pipes. All pipes have holes - this is necessary so that sound waves and gases pass through them and create resonance with each other. This is how exhaust gases are converted into gases and released outside the vehicle.

The resonator consists of two chambers and a perforated pipe that passes through both chambers

The mechanism from the Kalina can also act as a resonator for the Lada Priora. It has the same volume and the same design, making these elements considered interchangeable.

System breakdowns

There can be many problems with the exhaust system. As a rule, repair is not possible; replacement of elements will be required. Let's take a closer look at them.

Rust and system destruction due to corrosion. Accumulating condensate especially contributes to this problem.
Inability to muffle noise. Typically, the malfunction is caused by the destruction of the internal partitions of the main muffler.
Breakage of fasteners. A characteristic symptom of the problem is a knocking sound from the muffler and the appearance of vibration.
Oxygen sensor malfunction.

The standard method for solving certain problems is to replace the element. In some cases, temporary solutions are possible, but if the muffler is “burnt out” or rusted, unfortunately, you simply cannot do without installing a new part.

Malfunctions

The Priora exhaust system suffers mostly from corrosion processes that occur due to condensation: vapors settle on the hot surface, which, as the metal cools, turn into destructive drops. Overheating also causes system destruction. The main faults include the following:

reduced noise reduction;
breakdown of sensors;
broken fastenings;
mechanical defects of parts.

A decrease in the ability to suppress noise occurs due to damage to the partitions. This malfunction is usually indicated by rattling sounds when the engine is turned on. Whatever the malfunction, it requires an urgent procedure for replacing the muffler, because if you postpone this action until later, the problem can worsen and lead to very unpleasant consequences, because the muffler not only reduces the noise level, its second job is to protect against penetration toxic fumes into the cabin, which can lead to poisoning of the driver and passengers. In addition, the muffler affects the operation of the engine, maintaining its power. That is why it is important to approach the issue of replacing the muffler with the utmost care.

Replacing the resonator on a Priora, installation

As usual, to change the resonator you need a pit, or even an overpass. To carry out the replacement yourself, you need to prepare several tools and materials:

a set of keys;
penetrating lubricant;
chisel;
knob;
hammer.

Dampening vibrations and sound of the exhaust system is the main task of the resonator installed on the Lada Priora. Failure of the resonator is accompanied by increased levels of noise and vibration, which, in turn, reach their peak at high engine speeds.

This kind of problem brings discomfort not only to car passengers, but also to other road users. Repairing the Riorov resonator is not an appropriate measure, as a result of which a full replacement is necessary.

Roar, shooting, condensation and other reasons to look under the car

It's easy to spot muffler problems. It is difficult not to notice extraneous sounds coming from under the car, or a sharp change in the tone and volume of the response to pressing the gas. It is not uncommon to notice fluid leaking or even splashing from the exhaust pipe. All these are signs of malfunctions, but do they all indicate problems in the exhaust system?

Fluid in the muffler

Fluid dripping from the exhaust pipe is a common occurrence. However, it is worth distinguishing what kind of liquid it is. If it's water, there's nothing wrong with it. When the ambient temperature changes, moisture from the air condenses on the surfaces of the muffler. If a steel muffler is used, this can lead to corrosion, but usually the Priora exhaust system uses aluminized steel or stainless steel, which means that damage from water will be minimal. In cases of heavy accumulation of water, experienced motorists usually drill a drainage hole in the “barrel” of the muffler.

If there is excessive accumulation of water in the muffler, in winter you may encounter icing of the exhaust pipe

If antifreeze drips from the exhaust pipe, the fault should be looked for not in the muffler, but in the engine. The reason may be wear of the cylinder head gasket, as well as depressurization of the block itself. Antifreeze in the exhaust pipe is a symptom of serious problems, and if it is detected, you should immediately diagnose the engine.

Pops and shots from the exhaust pipe

Popping noises coming from the muffler indicate a malfunction. However, this is also a malfunction of the engine, not the exhaust system. Shots or pops from the exhaust pipe indicate that the mixture of air and gasoline does not burn out in the cylinder block, which means that when you hear them, you should check the spark plugs and spark plug wires, as well as the serviceability of the gas distribution mechanism. Problems with combustion of the mixture are not a symptom of a muffler failure, but they can be its cause.

Video: this is what pops from the muffler sound like

Knocking from under the car

A knocking sound from under the bottom of the car while driving or rattling from vibrations is an unpleasant phenomenon. The muffler may touch the gas tank or the underbody. There are several possible reasons for this.

First of all, check the rubber muffler hangers. Their wear leads to loosening of the entire exhaust system. These mounts are sold at most auto parts stores. Their price usually does not exceed 100 rubles per piece. Replace the suspension with new ones and the knocking will stop.
It is worth checking whether the clamp connecting the main muffler and the additional muffler is loose. If necessary, replace the fastening bolts and nuts. For replacement, it is best to use fasteners made of heat-resistant materials.
Using the wrong model of muffler with pipe bends that differ from the original spare part can lead to contact between the exhaust pipe and various components of the car: the body, the gas tank and even the suspension. Be careful when choosing a muffler.

Lowered the car - the muffler is knocking

When installing a short-travel suspension on a Priora, tuning enthusiasts often encounter a situation where the suspension beam, which has moved closer to the body, begins to touch the muffler. This problem can be solved by replacing the muffler hangers with new ones of a more suitable shape.

Loud roar at revs

If a vehicle's exhaust system loses its seal, it cannot effectively reduce the volume of exhaust emissions. In this case, the exhaust often takes on a “pseudo-sports” sound. Therefore, if the muffler growls, you should look for a gap in it. It can be on the muffler body or on the pipes. It makes sense to check the connections and their fastenings. If the metal from which the muffler is made is of low quality, the exhaust pipe may burn out due to temperature. Time, corrosion and the quality of domestic roads cause damage to the exhaust system.

Pressure and temperature can cause holes

A burnt or broken muffler is easiest to replace. If depressurization occurs at the joints, you can limit yourself to replacing the sealing ring and the necessary fasteners.

How to install new

After the old product has been dismantled, there is no need to rush to immediately put a new one in its place. First, you need to clean as much as possible of carbon deposits and dirt from all joints with the muffler and exhaust pipe. This will ensure better sealing of the entire system.

Further work is carried out in reverse order:

The new resonator is suspended on rubber hangers. If the rubber bands are stretched out, it is better to replace them with new ones, this will improve the fixation of the resonator.
Then you need to connect the resonator to the muffler.
Additionally, it is recommended to install a new reinforced gasket between them and secure it with bronze bolts, since only such connections will withstand high temperatures.
Then you can begin installing the resonator with the receiving pipe.
At the joints it is also better to install new nuts made of heat-resistant metal alloys.

Choosing a resonator is a problem for many car owners. Moreover, for the Lada Priora you can choose both original products and models from the Lada Kalina - there is no difference in design. You can save significantly on installation costs if you replace the resonator yourself. The procedure is quite simple and does not require special preparation. This is the only way the owner can guarantee the reliability of the fastenings and functions of the new resonator.

How to get rid of the problem

The muffler gasket is usually beyond repair. If the muffler gasket (ring) is damaged, it will have to be replaced with a new one. Replacing the gasket is fairly easy.

First of all, you need to get rid of the old gasket. You need to unscrew the two bolts that hold the flanges together. The bolts are usually rusty, making them quite difficult to remove. For this purpose, you can use a special tool (“liquid keys” or an angle grinder, if the situation is critical).
After the bolts are removed, you will have to carefully move the resonator tube to the left side.
The old muffler gasket is located on the resonator pipe. You will have to use a screwdriver to pry the product and remove it.
Next, you need to use a metal brush and sandpaper to remove carbon deposits from the flanges.
After this, the muffler gasket is replaced. The ring is installed on the resonator flange. The main muffler pipes are connected, and the flanges are screwed together using a clamp that has spring-loaded bolts that come in one set with a gasket.

The gasket (ring) of a car muffler is replaced in a fairly simple way. However, when removing the old gasket, it is important to take special care, because the cermet ring has a fragile structure, which is why it can easily break.

It is necessary to replace it in the event of a breakdown, because otherwise the car interior will be filled with fumes. Also, if a malfunction occurs, carbon deposits will begin to form under the very bottom, which will be very difficult to eliminate.

Twin Pipe Types

The following options are currently most popular among domestic car enthusiasts:

bifurcated outlet installed after the muffler;
parallel installation of two pipes with mufflers behind the resonator;
system with 2 resonators and the same number of mufflers.

Moreover, in the latter case, a twin pipe can also extend from each of them. As you can see, each option has its own advantages and disadvantages, so the choice remains with the car owner.

In this article we will tell you how to make the simplest double exhaust for a Priora. In this scheme, the pipe will be routed after the muffler, that is, the option is purely decorative.

This solution can be implemented in several ways. It will be easiest to weld a branch from the main pipe. However, this option has many disadvantages, which, however, do not affect the quality of the motor. But the fact is that at high speeds less gases will come out of the added pipe. That is, any knowledgeable person will understand that the dual exhaust is pure decoration.

It is better to assemble a structure in the shape of a slingshot, in which pipes of equal length and cross-section, directed in different directions, are installed after the muffler.

Mufflers VAZ 2110-(Tenth family)

Silencers by dozens are also divided into 2 body types:

Muffler VAZ 2110, 2111 – sedan and station wagon
Muffler VAZ 2112 – hatchback

And here too there are subtypes: new

and old style

. But unlike the Lada Samara, subtypes play a significant role here. Old style mufflers have a hook-shaped mount. Approximately, they were produced until 2007 (but not a fact - this is a VAZ, baby), then they came with pin-type fastenings.

Muffler corrugation Lada Priora

5 out of 5 (5 ratings)

* Calculated based on Yandex Directory reviews

Which muffler corrugation should I buy for Lada Priora? First, you need to know the size of the muffler corrugation. You can buy a muffler corrugation according to factory sizes, but when replacing the muffler corrugation, it turns out that you need to cut off a larger piece of the muffler pipe and the standard size will be insufficient. They buy a muffler corrugation when it has already burned out. The muffler corrugation is not repaired or welded.

The price of a Lada Priora muffler corrugation depends on the type of corrugation. There are two types of muffler corrugations: Interlock and Innerbraid. The most expensive and high-quality corrugation is Interlock: the corrugation consists of four layers, three outer layers and one inner layer. The second option is Innerbraid: three layers, both external. Frankly speaking, there is a difference between the corrugations, but it is not colossal.

In most cases, they buy a three-layer corrugation version. You may also need muffler rings and additional gaskets.

Price:

Knocking from under the car

First of all, check the rubber muffler hangers. Their wear leads to loosening of the entire exhaust system. These mounts are sold at most auto parts stores. Their price usually does not exceed 100 rubles per piece. Replace the suspension with new ones and the knocking will stop.
It is worth checking whether the clamp connecting the main muffler and the additional muffler is loose. If necessary, replace the fastening bolts and nuts. For replacement, it is best to use fasteners made of heat-resistant materials.
Using the wrong model of muffler with pipe bends that differ from the original spare part can lead to contact between the exhaust pipe and various components of the car: the body, the gas tank and even the suspension. Be careful when choosing a muffler.

Lowered the car - the muffler is knocking

Loud roar at revs

Pressure and temperature can cause holes

A burnt or broken muffler is easiest to replace. If depressurization occurs at the joints, you can limit yourself to replacing the sealing ring and the necessary fasteners.

Replacing the resonator yourself

For what reasons do parts of the exhaust system fail? Each Lada Priora car owner can list at least three factors that affect the service life of the resonator:

mechanical damage to the body due to road unevenness;
corrosion;
metal fatigue.

High humidity, temperature changes in winter (the inside of the resonator can be very hot, while it is cold outside), accumulation of condensation - all this affects the service life of the product. First, the resonator begins to roar loudly and scare people passing by. Then the owner of the Priora receives complaints from his neighbors, whom he disturbs in the morning when he starts his car.

One way or another, a powerful roar is only the first step towards resonator malfunctions. Then it becomes deformed, cracks and holes form on its body, which makes the car unsafe to operate.

Tool preparation

Due to the fact that all parts of the exhaust system are constantly exposed to temperature changes, you will need tools that can be used to knock out or break off a bolt or nut stuck to the body. So, you need to prepare in advance:

two open-end wrenches for 13;
ratchet;
hammer;
chisel;
WD-40 or brake fluid for lubrication.

Tools for replacing the resonator can be found in every car enthusiast's garage.

How to determine whether a muffler is faulty

In fact, this is the element that is most often exposed to high temperatures. Over time, this element fails due to corrosion, burnouts, impacts on uneven roads, or constant accumulation of condensate in the pipe .

Corrosion causes the muffler body to lose its seal.

If the muffler is faulty, the driver will immediately notice this:

the “glushak” will start knocking on the body;
the car will lose its dynamism;
you can hear pops and a strong roar in the exhaust pipe;
Antifreeze is leaking from it.

Why does the silencer fire?

Most often, car owners complain about loud popping noises in the exhaust system while driving. The muffler can only fire for one reason: the air-fuel mixture does not have time to completely burn out in the engine, so ignition occurs in the exhaust pipes.

This can seriously damage the integrity of the pipes. Therefore, at the first claps, you need to check the following car systems:

spark plug wires (if, after replacing the spark plugs, the wires were connected incorrectly, problems with engine operation may occur);
gas distribution control;
timing belt performance.

That is, the occurrence of pops is not related to the performance of the muffler itself, but directly affects the service life of the pipes.

Knocks from under the body

The muffler may knock:

about the bottom of the car;
about the fuel tank body.

In any case, the impact of the pipe on the surface quickly deforms the coating, as a result of which the part loses its tightness. There are two reasons why it lost its original position under the body and began to hit other surfaces while driving:

The rubber suspensions are worn out. You just need to buy new rubber bands and replace them. The muffler will return to its normal position and the knocking will stop.
After replacing any elements of the exhaust system. It is quite possible that certain parts were connected incorrectly, the nuts were not tightened correctly, the reinforced gasket was inserted on the wrong side, etc. To understand this problem, you will need to carefully check all connections and elements. Often knocking noises occur due to improper installation of the short stroke.

Antifreeze in the muffler

Antifreeze that drips from the exhaust pipe may indicate one serious problem with the engine - wear of the cylinder head gasket. Therefore, coolant gets inside rather than being used in the cooling system.

It is recommended to immediately take measures to diagnose the engine unit.

Condensation accumulates in pipes

Drivers often notice a phenomenon such as water in the exhaust pipe. Sometimes condensation appears even in winter. Of course, for steel pipes of the exhaust system, moisture is considered the main enemy - here it’s not far from corrosion.

However, the formation of condensate in pipes is an irreversible process. This cannot be called a malfunction or defect of the exhaust system, since due to high temperatures inside the pipes and lower temperatures outside, the exhaust gas turns into a liquid state. This is why condensation forms. Some drivers drill small holes in the muffler to make water leave the muffler faster. This really helps prevent corrosion from developing quickly.

This phenomenon can often be observed on all cars.

Manufacturers and prices of analogues - how much the part costs

The question of which resonator is best to install on the Priora should be approached based on requests. For example, parts for sports cars are completely tailored to maximize engine power. Such components process a larger volume of gas over a period of time than standard parts. They remove hot gases from the space around the engine faster and it cools faster, and the fuel-air mixture is cleaner, while the proportion of “dirty” air is noticeably reduced. The following analogues are suitable for Lada Priora:

Mute (for spider) – 3,200;
Mute (with spider corrugation) – 4,400 rubles;
Stinger Sport (for spider) – 1,500 – 2,000 rubles;
Stinger Sport (without flanges) – 2,100 rubles;
Stinger Sport (FSA class with corrugation) – 3,300 rubles;
Stinger Sport (with corrugation on a triangular flange) – 2,400 rubles;
Turbotema with spider corrugation – 2,600 rubles;
Turbotema for spider – 1,100 rubles;
STT with corrugation – 5,500 rub.

How to repair a muffler

If your car's muffler requires repair or complete replacement, it is not recommended to do this work yourself, since there is a high risk that you will only worsen the condition of the exhaust system, and possibly the entire vehicle as a whole. In order to prevent such a situation, contact only specialized car services. In our car service center, qualified specialists with the necessary competence in the field of working with exhaust systems will competently diagnose the exhaust system of your car, and, if necessary, repair or install a new muffler in the shortest possible time.

Which model is better to choose

Choosing a new device is almost always a challenge. Firstly, I want to save money on its purchase. Secondly, in order to avoid paying attention to the operation of the exhaust pipe for a long time, it is advisable to buy a more or less high-quality product.

Today, several models for the Priora are presented in car markets and auto stores at a variety of prices. The cost of any product depends on its quality. So, on free classifieds websites you can buy a used resonator for about 450–550 rubles. However, at a low price, the car enthusiast acquires an additional problem: the resource of such an element has already been exhausted and it does not have long to serve.

The middle price category includes resonators produced by AvtoVAZ - Lada Image. They are made of durable metal alloys and can last for quite a long time - up to 5 years. Their average price ranges from 1500 to 2500 rubles. The cost increases according to the thickening of the metal wall and the number of perforated tubes inside the housing.

The Lada Image resonator is capable of providing factory quality at an affordable price

And also in the category of “middle peasants” are Ecris resonators. They come in two types - regular and aluminized. Their performance indicators and service life are almost the same as those of Lada Image.

The Phobos models are recognized as the highest quality. They are made using rolling technology, that is, they have excellent tightness and durability characteristics. Depending on the financial condition of the buyer, you can choose a regular housing or a device with a corrugated compensator, which will reduce exhaust noise to a minimum and will serve for more than 10 years. True, such models cost 3500–4000 rubles.

The Phobos resonator is chosen by drivers who are accustomed to trusting only proven brands

When choosing a new resonator, one must proceed from practical convictions: the product must meet all safety requirements. Some car enthusiasts try to make a resonator for the Lada Priora with their own hands: this is a fairly simple procedure, however, a homemade element is not always completely sealed and removes gases from the manifold well.

A reliable and high-quality resonator will ensure stable removal of gases from the manifold and prevent the penetration of poisons into the cabin

What does the price depend on?

To manufacture the body and tubes of high-quality components, special stainless and heat-resistant steels are used, designed to operate under constant thermal load with sudden temperature changes. These mufflers last longer, but they are the most expensive. Spare parts made of aluminized steel or aluminum-zinc will also last a long time. To reduce the cost, “ferrous” alloys are sometimes used.

The larger the muffler volume, the better. Other factors that increase the service life and increase the cost of the unit are thicker walls and complex internal design, as well as additional thermal protection.

Direct-flow muffler for Priora

Which muffler should I put on the Priora?

The need to repair the exhaust system arises for any car. The action of high temperatures, high humidity, reagents and salt on the roads in winter, all this leads to the destruction of the metal from which the exhaust parts are made. Let's take a closer look at the questions: which muffler to buy for a Priora (VAZ 2170 - VAZ 2172), which resonator to install on a Priora, how many parts does a muffler on a Priora consist of, and how much does the exhaust system on a Priora cost in current realities?

There are options for cheap Ukrainian-made mufflers, there are spare parts that are more expensive than foreign ones, and you can install a direct-flow (sports) exhaust. If you are faced with the problem of repairing the exhaust, we will look at how to replace the muffler on a Priora below in various possible variations.

What parts does the Priora exhaust system consist of?

The exhaust system of a Priora car (VAZ 2170 - VAZ 2172) consists of the following components:

collector pipe: as standard, it has a catalyst or particulate filter, which allows it to meet the environmental safety requirements of the car Euro - 3, and later, in the latest models, Euro - 4; the collector is connected through flanges to the resonator

The resonator is equipped with an integrated corrugation, which allows you to reduce the level of vibration in the exhaust, this is important for Priora; the resonator is connected to the muffler through a clamp, this allows you to quickly remove the Priora muffler if it needs to be replaced; from the rear of the car, from the outside, you can see the muffler exhaust pipe, which many motorists decorate with an aesthetic nozzle; all the main components of the Priora exhaust system are connected using pipes into a single, closed and sealed system.. It has become quite common to replace the manifold with catalyst with a regular spider (exhaust pipe) familiar to classic VAZs.

In this case, environmental standards are not complied with absolutely, but the catalyst does not “strangle” the engine. By reflashing the electronics, you get an increase in power and better vehicle dynamics at certain engine operating modes

It has become quite common to replace the manifold with a catalyst with a regular spider (exhaust pipe) familiar to the classic VAZ. In this case, environmental standards are not complied with absolutely, but the catalyst does not “strangle” the engine. By reflashing the electronics, you get an increase in power and better vehicle dynamics at certain engine operating modes.

Most often in Priora there is a need to change the muffler. If an unpleasant loud sound appears when the engine is running, then the most likely cause is a burnout in the muffler. A situation often arises when the exhaust system cracks when the Priora accelerates. The most common reason for this situation is the destruction of the internal partitions in the muffler bank. At certain engine speeds this has a noticeable effect on the sound. In any such situations, the best solution would be to install a completely new muffler on the Priora.

Device

As we said above, the Priora exhaust has three main elements. Let's look at each of them in more detail:

leading muffler. Elliptical device made of high-strength metal. In the inner part there are partitions necessary to soften the sound. There are pipes connected to it in front and behind. It is fixed to the body with the help of special pillows that prevent vibration;
additional muffler. It is located near the manifold and is fixed to the body similarly to the leading structure. The connection to the leading muffler is made using hinges, which helps prevent damage to the bottom and lighten the load on the device;
collector. Necessary for collecting exhaust from the engine and to prevent damage to the metal by harmful reagents. Connects to the receiver using flanges.

So, we have figured out the structure of the system, then we will talk about its main problems.

Standard muffler - article number and price

The VAZ 2170 Priora is equipped by the factory with spare part item number 2170-120010. Made of light sheet steel with a thickness of 0.8-1.1 mm. Connecting inlet pipe with a diameter of 48mm. Inside the muffler chamber (an oval tank - popularly known as a barrel) there is a series of parallel chambers for the last stage of dampening the force of the sound wave of the exhaust gases. The exhaust pipe allows you to install different types of muffler attachments to add uniqueness and change the sound characteristics of your car's exhaust. The price of such a standard muffler is in the range of 1200-1600 rubles. Of course, you can go much further.

The feasibility of installing a new stainless resonator

This is how Priora sounds without a resonator

For the purpose of high-quality replacement and long-term use, it is necessary to install a stainless resonator on the VAZ 2170 Priora. Installation of such a resonator occurs in a standard place. Lada Priora replacement of the resonator eliminates the need for modifications and improvements to the exhaust system.

This type of resonator has two parts, namely internal and external. Both parts are stainless steel (AISI 316 steel). AISI 316 steel is a common analogue of 10Х17Н13М2.

The standard resonator, which requires replacement, has dimensions of 250x100. Pipe size – 51x1.5. The pipe is also made using AISI 316 steel.

Which muffler to choose

Stainless steel or aluminized steel

Mufflers for cars of the Priora family are made of steel of various thicknesses. The thicker the steel, the stronger the muffler. The type of steel is no less important. Most car enthusiasts prefer stainless steel that has been proven over the years. However, modern aluminized steel is not inferior to it in terms of resistance to corrosion, and is significantly superior in overall strength and ability to absorb vibrations. This means that an aluminized steel muffler will be quieter than a similar one made from stainless steel.

Manufacturers and prices

Exhaust system parts for Lada-Priora cars are produced not only in Russia. There are mufflers and resonators made in Poland, Turkey and Germany.

A muffler for a Priora costs from one to five thousand rubles. At the lower end of the price range are models made of thin steel; aluminized models usually cost at least three thousand rubles. The situation is similar with resonators. Prices for them start at about one and a half thousand rubles.
